Cement Ball Mill Sizing Explanation The Cement Grinding Office. This method only gives a rough and initial idea for sizing a cement ball mill. To go ahead, a deeper ... The wellknown Bond formula used is the following: .... In the cement industry, the dry process is always used except some old. installations ....
It is assumed that the ore is continuously discharged from the feeding port to the discharge port. The ball milling time calculated under this ideal state is the minimum grinding time. The filling rate of the ball mill is 40%. If the slurry level reaches 50% filling rate, the slurry will flow out automatically.
Our OK Mill grinding solution skilfully comminutes raw material, cement and slag. You can easily adjust it to grind any feed material and produce multiple cement types in the same mill. Due to its highly effective drying performance, the OK Mill is the natural choice for grinding blended cements with one or more wet components.
Please find below two calculators for sizing mills using the Bond and Rowland methods: Ball mill sizing: Calculator for ball mill(s) in a single stage circuit. Rod ball mill sizing: Calculator for rod mill(s) as first stage of the circuit and ball mill(s) as second stage of the circuit.
Ball Mill Power Calculation Example #1. A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns).
Overview. The ball mill for clinker is an efficient tool for fine powder grinding. It is mainly used to grind the clinker and raw materials in cement industry and also can be applied in metallurgy, chemical, electric power and other industries to grind all kinds of ores.
the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. Power drawn by ball, semiautogenous and autogenous mills A simplified picture of the mill load is shown in Figure Ad this can be used to establish the essential features of a model for mill .
A comparison between the grinding systems and conventional ball mills applied in cement grinding circuits is given in Table 5. Grinding efficiencies of different systems in grinding of cement to a fineness according to a Blaine of 3,000 cm 2 /g were compared in Table 6.
Several energy efficient options for cement grinding are available today such as vertical roller mills, roller presses (typically in combination with a ball mill), and clinker pregrinders with ball mills. Ball mills have been the traditional method of comminution in the mineral processing industries and continue to operate with old generation ...

The Power Consumption Calculation of a Ball Drum Mill IDOSI Current methods of power consumption calculation of a mill drive do not allow Key words: Ball drum mill Grinding media Material grinding Grinding efficiency Mode of grinding media Currently, best examples of ball drum mills in cement.
In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case".
Jun 25, 2018· Mill effective diameter = m . 335 is a constant used for dry grinding with steel balls in the mill. Actual size of media is taken is lower than the calculated value. It is around 80 to 90 mm. If you Wants to reduce the maximum ball size, thenreduce the feed size by using pregrinding operation.
